Ways to save in Fort Worth

Build up or bump out rather than adding a new foundation footprint.
Keep plumbing on the existing wet wall — moving water and waste lines is the costliest change.
Convert existing space (garage, attic, basement) at half the per-square-foot cost.
Keep the roofline simple; complex tie-ins add framing labor and leak risk.
Lock the design before demolition — change orders during construction carry the biggest premiums.
